    a.

    Step-by-step explanation:

    A and B both are greater than mean and so A and B lies on the right side of mean. Further it is stated that A is more away from the mean than B. It means that A is greater than B. So, in order to find the area between A and B we have to subtract the area of mean to B from area of mean to A. It can be explain in the notations as

    P (B
    P (B
    Hence, we find the area from mean to A and subtract the area from mean to B.
